At Eawag, the aquatic research institute, numerous scientists are conducting research into toilets. In short videos, seven of them explain what fascinates them about the topic and what exactly their research is all about.
In Switzerland, going to the toilet is an everyday occurrence. Not so in other countries. Even today, over two billion people still have no access to sanitary facilities. There are many different reasons for this: lack of financial and human resources, poor planning, lack of water, or even socio-cultural norms. Eawag is therefore conducting research into new planning methods and concepts to solve this challenge in a sustainable and fair manner.
Modern toilets also open up new possibilities for recovering nutrients, water and energy from wastewater. Eawag is therefore developing systems and technologies for toilets to enable valuable resources to be recycled.
To mark World Toilet Day on 19 November, we asked Eawag researchers what interested them about toilets, their use and further development, and what they were currently researching.
